1. INTRODUCTION 1.1 INTENT

The Park and Recreation Department has developed the Consultant’s Guide to Park Design and Development (Consultant’s Guide) to establish general standards, guidelines and criteria for the design and development of improvements in City parks and open spaces. The Consultant’s Guide is not a substitute for professional experience. Sound judgment must be exercised in the application of the standards to specific circumstances. The standards do not preclude the use of different methods when special conditions or site specific conditions are a factor and when proper authorization is obtained.

The Park and Recreation Department encourages “partnering”, the creation of a relationship between the Park and Recreation Department, the City Project Manager and the Consultant, which promotes achievement of these standards and quality parks. In this respect, City Project Managers and Consultants are encouraged to take the time at the start of a project to identify common goals, lines of communication and a commitment to cooperative problem solving.

If a major deviation from the standards is necessary or desirable the, the Park and Recreation Department shall be informed in writing so the change can be evaluated for approval, and as a possible future revision to the Consultant’s Guide. Any deviations from the standards established in this Consultant’s Guide must be approved in writing from the Park and Recreation Department.

1.2 GOALS

The Park and Recreation Department ensures quality parks by basing designs on the following goals:

Aesthetics: Parks should project a positive image and establish a permanent character for the community and City. Park designs should provide a sense of arrival with reference points to promote circulation. They should provide places for groups and individuals for both formal and impromptu events. They should indicate nature through seasonal changes and provide something unique, obvious, complex and simple. They should provide human and monumental scale and should be visible from a distance. Overall, a sense of place and community should be created through the design of each Park.

Function: Parks should be designed for all community members to use and enjoy the facilities. Parks must also be functionally designed for the people who maintain the facilities. The most current products and industry standards should be applied to the park’s design.

Economics: Parks should be designed for the allocated budgetary considerations and to provide economical means of maintaining the park.

2

1.3 APPLICATION

The Consultant’s Guide applies to all parks, rights-of-way, maintenance assessment districts (MADs), gas tax medians and open spaces that are to be maintained by the Park and Recreation Department or a City Maintenance Assessment District. This includes all new parks, retrofitting existing parks, (Capital Improvement Projects), parks built using public funds (referred to as Public Projects), parks built using private funds and turned over to the City (referred to as Turn-Key Projects or Developer Built Projects), parks that are part of a joint use agreement and parks within City open space areas.

1.4 OTHER REGULATING DOCUMENTS

The design of parks shall also include the standards and requirements of the cited reference documents found in Appendix C. If conflicts arise between the Consultant’s Guide and other governing documents, contact the Park and Recreation Department for clarification.

1.5 DESCRIPTION OF CHANGES

In general, the 2010 Consultant’s Guide to Park Design and Development has been updated to reflect current local, State and Federal requirements. Formatting and numbering has changed as well. Park and Recreation standard details have been updated and added to the Appendix.

1.6 TYPES OF PARKS

The City of San Diego provides numerous types of parks for residents and visitors: 1) Resource-Based Parks, 2) Population-Based Parks, 3) Special Recreational Parks, 4) joint use parks, 5) Maintenance Assessment District parks, and 6) open space parks. Resource-based parks serve users from the entire city and elsewhere, and are located at or centered on natural or man-made features. Beaches (Mission Bay Park), historical sites (Balboa Park), and natural canyons and water courses (Mission Trails Regional Park), are examples of this type of park. Population-based parks are intended to serve the local daily needs of residential areas. Where possible they adjoin schools in order to share facilities, and ideally are within walking distance of the residences within their service area. The City also provides other special and smaller recreational parks that are neither population-based nor resource-based; these include developed parks within open space, plazas, large and small landscaped areas, and pocket parks. Joint use parks are partnerships between the City of San Diego and a school district wherein the contributions of land, improvements and maintenance are shared equally to provide the community and school with enhanced recreational opportunities. Maintenance Assessment District Parks are generally parks that are provided above and beyond the requirements identified in the General Plan, and are maintained through a special assessment of nearby property owners. Open space parks are undeveloped City-owned lands consisting of canyons, mesas and other natural features, and provide passive recreational trails for hiking, biking and horseback riding.

3

1.6.1 Resource-Based Parks: Resource based parks are intended to preserve and make available to the public areas of outstanding scenic, natural, or cultural interest. They are meant to supplement the neighborhood and community parks, and they serve the entire City and its visitors rather than any one community. However, they can also function to fulfill local neighborhood and Community Park needs of surrounding residents.

1.6.2 Population-Based Parks: Population-based parks are divided into two categories: Community Parks and Neighborhood Parks.

Community Parks: Community Parks typically serve 18,000 to 25,000 residents within approximately a 1-1/2 mile radius. Ideally they should have at least 13 useable acres when adjacent to a school, or 20 useable acres when not adjacent to a school (“useable acres” is defined as being two percent or less in grade). They should provide a wide range of facilities that supplement those of the neighborhood parks and which are determined by the needs and preferences of the community. Recreation centers, athletic fields, multipurpose courts, picnic facilities, play areas, parking areas, and comfort stations, landscaping and turf areas are standard amenities. When possible and desirable, swimming pools and tennis courts may be provided.

Neighborhood Parks: Neighborhood Parks serve a resident population of 3,500 to 5,000 persons within approximately a one half mile radius. Ideally, they should have a minimum useable area of five acres when located adjacent to a school or ten useable acres when not adjacent to a school. The design and type of facilities should be determined by the population and use characteristics of the neighborhood. Play areas, multi-purpose fields, comfort stations, multi-purpose courts, picnic facilities, landscaping and turf areas are typical amenities in neighborhood parks.

1.6.3 Special Parks: Special Parks are smaller than community or neighborhood parks (two acres or smaller) and contain passive recreation activities. These parks are sometimes called ‘Pocket Parks’, Renaissance Parks or ‘Mini-Parks’, and are often built by a Developer as a condition of a Land Development Permit and then turned over to the City to maintain. Walkways, trails, benches, shade structures and small play areas are typical amenities of these parks.

1.6.4 Joint Use Parks: Joint use parks are found adjacent to a population-based park and a school, or may be found adjacent to a school only. The costs of land, development and maintenance are shared equally by the City and the school district. Joint use parks are designed and constructed to the standards of the Consultant’s Guide when the City will be responsible for long-term maintenance. A Joint Use Agreement between the City and the school district will be processed by the City.

4

1.6.5 Maintenance Assessment District (MAD) Parks: Maintenance Assessment District (MAD) parks are special parks that are maintained through an assessment of nearby property owners that is levied annually. Maintenance assessment districts maintain a variety of landscaping features, including certain parks and streetscapes. In cases where a maintenance assessment district maintains a park, typically the additional park is above the City’s standard identified in the General Plan. Most maintenance assessment districts also maintain streetscapes, which typically include enhanced improvements along a public right of way, including street trees, greenbelt landscaping, center median landscaping, planted slopes, decorative benches and trash receptacles, decorative paving, enhanced street lighting and trails that are typically adjacent to public rights-of-way.

1.6.6 Open Space Parks: Open space parks are land which is owned by the City consisting of canyons, mesas and other natural landforms. Open space parks are intended to preserve and protect native plants and animals while providing public access and enjoyment by the use of hiking, biking and equestrian trails. Open space parks generally have minimal development and are intended to remain in their natural state.

2.16 IRRIGATION

2.16.1 General Requirements

(1) Irrigation System Efficiency: The irrigation system for turf areas shall be designed to achieve a Distribution Uniformity (DU) of 70 percent, or 0.70. To achieve this goal, the irrigation system shall be audited by an independent Certified Landscape Irrigation Auditor, certified by the Irrigation Association. Deficiencies shall be corrected prior to the start of the Plant Establishment Period. These requirements shall be included in the construction documents.

(2) Irrigation Design: The irrigation system shall be designed utilizing water conservation standards and equipment. The irrigation design shall be based on accurate pressure information and produce an irrigation system which efficiently and uniformly applies water throughout the site. The irrigation design shall also have sufficient residual pressure and flow to accommodate site conditions, field changes and unforeseen future demands as well as anticipated future demands, if it is a phased project.

(3) Watering Schedule: For most parks there are two primary considerations: 1) To assure that the irrigation design will meet the time constraints of the park’s required operation needs; and 2) The system must be able to apply the volume of water necessary to achieve the evapotranspiration rate (ETO) for the highest demand month within a 32 hour per week watering “window.” For parks with active sports fields it is critical the irrigation design is adequate to irrigate the site within the irrigation window and the recreational schedule of the sports fields. The irrigation design must be able to irrigate the complete site within one 8 hour irrigation window. This cycle must be able to apply the volume of water needed in a peak summer condition following two consecutive days of no water. A typical condition at most sport field complexes requires that the fields not receive irrigation on Friday or Saturday nights in preparation for community use on the following morning, and therefore the irrigation design must apply three days of irrigation in a single night. To carry overtime for this condition is NOT effective.

30

(4) Residual Pressure: In developed areas the residual pressure shall be 15% and in undeveloped areas the residual pressure shall be 25% of the required operating pressure.

(5) Ball Field Irrigation: Irrigation circuits for ball fields shall be separated from other turf areas of the park.

(6) Slope Irrigation: Irrigation lines shall run horizontally (level and parallel to the slope contours) to minimize line drainage and pressure differentiation.

(7) All irrigation equipment shall be installed per San Diego Standard Drawings unless otherwise noted or detailed on the construction drawings. Deviation from the San Diego Standard Drawings must be approved by the Park and Recreation Department.

2.16.2 Recycled Water: The irrigation designer shall verify the need to design the irrigation system for recycled water use with the appropriate water district. All recycled irrigation systems shall be designed per the ‘Rules and Regulations for Recycled Water Use and Distribution within the City of San Diego.’

(1) Cross Connection Test Station: Shall be a cast brass or bronze ball valve, 3/4 inch female thread, installed in a concrete valve box with a cast iron locking lid.

(2) Quick couplers and manually controlled high-speed rotor heads provided for softball field dust control identified in Section 2.14, Multi-Purpose Fields, shall be connected to a potable water supply with adequate backflow protection.

2.16.3 Irrigation Controllers

(1) Irrigation systems shall be controlled by an automatic electrical controller.

(2) Controller Locations: Controllers shall be installed at locations approved by the Park and Recreation Department. The preferred location is wall-mounted inside a Park and Recreation storage room of a comfort station, recreation center or other permanent park building. When a comfort station, recreation center or other park building is not present, the controller(s) shall be installed in a controller enclosure located in a shrub or mulch area; do not install irrigation controller enclosures in turf areas.

(3) Interior Mounted Controllers: When located inside a Park and Recreation storage room or other acceptable space, the irrigation controller(s) shall be mounted on a pre-assembled controller and backboard assembly.

31

PARK AND RECREATION BOARD POLICY

SUBJECT: Naming of Parks and Recreation Facilities

BACKGROUND: The public sometimes suggests that parks and recreation facilities be named after persons, living or dead.

PURPOSE: To provide a systematic procedure for the naming of parks and recreation facilities, which will assist in their location by the citizenry, and to develop a method for the retention of names of historical or fiscal significance.

POLICY: As a general policy, parks and recreation facilities should be named to identify their locations. Especially for parks, the name of the community area, the names of nearby geographic features, the names of adjacent schools and street names should be given first consideration. However, they may also be named for individuals, living or dead, who are of historical significance to the local area or who have made major financial contributions in the opinion of the appropriate Recreation Councils and/or other advisory bodies, Board committees and the full Board. Facilities within parks, (such as buildings, gyms, courts, etc.) are more appropriate for naming after individuals than are parks.

Renaming a facility for a person, when that facility is already named for a person, should only be undertaken with the utmost consideration. Every attempt should be made to contact the person or heirs of the person for whom the facility is currently named, to present their views verbally, or in writing, at a public hearing.

PROCEDURE: The Recreation Council effected by the proposed name change, shall hold a public hearing to review the request and the supporting documents and information, and shall make recommendations to the Area Committees and the Park and Recreation Board on any and all recommended changes to the renaming of existing facilities.

PARK AND RECREATION BOARD POLICY

SUBJECT: Graphic Presentations for the Park and Recreation Board and Committees

BACKGROUND: Graphic presentations showing preliminary designs of parks, park improvements, park related structures and facilities are regularly submitted for review and approval by the Board and its sub-committees. These graphic presentations are often the only occasion on which the Board will review and recommend approval of a project.

PURPOSE: The purpose of this policy is to establish a minimum graphic standard for use by architects, landscape architects, other consultants and staff for presentation to the Park and Recreation Board and Committees.

POLICY: 1. Presentations shall be as clear and simple as possible while still describing the total scope of the project.

2. Presentations shall be of sufficient scale and size to be easily viewed from fifteen to twenty feet away.

3. Presentation drawings shall be mounted on minimum sized 30 inch by 40 inch boards. Loose or rolled drawings are not acceptable.

4. Presentation drawings will include but not be limited to the following (as applicable):

a. A location map.

b. A topographic or grading plan which clearly indicates existing and proposed contours.

c. A development plan clearly indicating on-site facilities including buildings, parking areas, play areas, lighting, landscape materials, drainage, and utilities. This plan should be in color. Critical dimensions should be included.

d. Building presentations will include floor plan, all elevations to clearly describe the structure. The drawings shall be colored. A perspective drawing may be submitted at the Consultant’s option.

5. Photographs of the site and the surrounding areas, if required to define unusual topography or features, are recommended.

APPENDIX A

CITY OF SAN DIEGO, CALIFORNIA

COUNCIL POLICY

SUBJECT: COMMUNITY NOTIFICATION AND INPUT FOR CITY-WIDE PARK DEVELOPMENT PROJECTS

POLICY NO.: 600-33 EFFECTIVE DATE: September 29, 2003

BACKGROUND:

The community review process has been generally successful in gathering input on park development projects. However, this process has become very time-consuming, and staff intensive, resulting in unnecessary impacts on project funding and timelines.

PURPOSE:

The purpose for this policy is to assure that community members have adequate advance notification and opportunity to participate in the design phase of park development projects. It is intended that the process be administratively efficient, structurally predictable, and result in timely community input.

POLICY:

Community Notification: This process is designed to achieve early notification of community members to allow for timely input on park development projects.

In preparation for the community input phase of the project, the project manager will develop a project notification bulletin. This bulletin will include the project location, the proposed scope of work, the goals for the upcoming meeting, time and location of meeting, contact information regarding questions, information regarding posting of the staff report at the community recreation center or park kiosk and any available web site information relevant to the project.

The project manager will also prepare a staff report. This will include additional project information regarding the community concerns and issues, funding limitations and any additional relevant information.

The project manager will notice the officially-recognized recreation council or open space citizen’s advisory committee prior to the first community meeting through the following steps:

1. Project manager will notice the staff representative and each member of the officially recognized recreation council or open space citizen’s advisory committee with the project bulletin and staff report.

2. Project manager will notice the appropriate City Council office(s) with the project bulletin and staff report.

APPENDIX B

B-7

CITY OF SAN DIEGO, CALIFORNIA

COUNCIL POLICY

3. Project manager to notice the officially-recognized recreation council or open space citizen’s advisory committee with a project bulletin and staff report which will be posted.

4. Project manager will notice the staff representative to the City-recognized local community planning board/group and each community planning board/council member with the project bulletin inviting them to attend the community meeting.

5. Prior to the first community meeting, the project manager will contact the appropriate council office(s) staff representative(s) to seek names of community members who have expressed interest in the proposed project or site. Project manager will notice these community members with the project bulletin.

6. Project manager will coordinate the creation and posting of a sign or community notice at the subject park site identifying the upcoming community meeting and contact information.

7. Project manager will notice surrounding park neighbors within a minimum 300’ radius of the park or project site for projects that will be significantly increasing the number of users at the site, for example, a new community or neighborhood park, new joint use areas, visitor center or new lights at an existing site.

For additional notification, the project manager will discuss the next steps for the approval for the project at each community meeting and compile a list of community members who have expressed interest in the project. Based on this list the project manager will contact community members regarding additional community meetings during the design approval process.

Community Input Process: Community meetings should efficiently utilize community members’, staff and consultants’ time. The meetings should be well organized with a clear purpose. The officially-recognized recreation council or open space citizen’s advisory committee will be the sponsor for local community input. Park development projects should be presented to the local community two times receiving a recommendation from the officially-recognized recreation council or open space citizen’s advisory committee at the second meeting. The input process should include the following steps:

1. In preparation for the first meeting, the project manager will prepare project information that outlines the roles for the design team and community members, the anticipated scope of work, the project budget and funding sources, and projected time schedule. With this information, the officially-recognized recreation council or open space citizen’s advisory committee

APPENDIX B

B-8

CITY OF SAN DIEGO, CALIFORNIA

COUNCIL POLICY

provides input regarding the development of a preferred project program, as well as a community priority ranking of the proposed program elements. This information will give the design team clear direction regarding community desires and will be used to develop conceptual alternatives that maintain community priorities and the project budget.

2. These conceptual alternatives are presented to the officially-recognized recreation council or open space citizen’s advisory committee and community at the second meeting. At this second meeting, the community will have an opportunity to review and comment on the proposed alternative plans. Community members will be allowed to: a) recommend individual elements from the conceptual alternatives to be synthesized into a preferred alternative plan, or b) endorse the presented conceptual plan that best meets the outlined project program and priorities identified by the community. Complex projects, such as new community parks or the design for a new recreation center may require an additional meeting with the officially-recognized recreation council or open space citizen’s advisory committee. Cost estimates and schedules will be based on the process outlined in this policy. Any additional meeting(s) beyond those outlined will impact the project by increasing the project timeline and reducing the funding available for construction.

3. Following a recommendation from the officially-recognized recreation council or open space citizen’s advisory committee, the design team will incorporate the proposed revisions and prepare a preferred project plan for review and recommendation by the appropriate review committees and boards. Each of these committee and board meetings are public meetings and they provide additional opportunities for community input. These additional review committees could include:

a. SCRAB- Sub-Committee for the Removal of Access Barriers b. FARB – Facilities Access Review Board c. Park and Recreation Board – Area Committees d. Park and Recreation Board – Design Review Committees e. HRB – Historical Resources Board design assistance sub-committee f. HRB – Historical Resources Board

It is intended that each of these committees and boards will require one meeting, assuming all applicable project information is accurately compiled and presented in accordance with Park and Recreation Board Policy No. 1011 and submittal standards established in the Consultants Guide to Park Development. Each of these committees and boards will make a recommendation on the

CITY OF SAN DIEGO, CALIFORNIA

COUNCIL POLICY

SUBJECT: SUSTAINABLE BUILDING POLICY POLICY NO.: 900-14 EFFECTIVE DATE: May 18, 2010

BACKGROUND:

The passage of the California Global Warming Solutions Act of 2006 (Assembly Bill 32) and other pivotal legislation and policy in California - such as the establishment of statewide energy efficiency goals (AB 2021), Low-Income Energy Efficiency statutes, the Governor’s Green Building Executive Order, the California Energy Commission Integrated Energy Policy Report (2007), and the CA Public Utilities Commission (CPUC) Strategic Plan (2008) - create an environment where energy efficiency efforts must not only continue to thrive but scale up at unprecedented levels. The four specific programmatic goals, known as the “Big Bold Energy Efficiency Strategies,” established by the CPUC include:

1. All new residential construction in California will be zero net energy by 2020;

2. All new commercial construction in California will be zero net energy by 2030;

3. Heating, Ventilation and Air Conditioning (HVAC) will be transformed to ensure that its energy performance is optimal for California’s climate; and

4. All eligible low-income customers will be given the opportunity to participate in the low income energy.

The 2003 update of 900-14 requires City projects to achieve the U.S. Green Building Council’s LEED silver standard for all new buildings and major renovations over 5,000 square feet. The City of San Diego General Plan (2008) and the City of San Diego Climate Protection Action Plan (2004) formalizes the commitment to increase energy efficiency and the use of renewable energy. In order to achieve the goals in the CPUC Strategic Plan and the City’s General Plan, more substantial requirements are needed as a bridge to zero net energy in 2020 (residential) and 2030 (commercial). To that end, the Sustainable Building Policy will be updated every three years to remain current with new State and Federal guidelines and local needs.

PURPOSE:

The purpose of this policy is to reassert the City’s commitment to green and sustainable building practices, and applies to new construction or major renovations that the City owns, occupies or leases. A major renovation is defined as an alteration or renovation to existing conditioned spaces that are 5,000 gross square feet or larger in area and require at least two energy building system changes. The site boundary for the scope of this Policy is the contract limit line of the work included in the Major Renovation project. (See Definitions, page 5-6) The

APPENDIX B

B-11

CITY OF SAN DIEGO, CALIFORNIA

COUNCIL POLICY

Sustainable Buildings Policy shall recognize projects that are designed, constructed and operated using cost-effective innovative strategies and technologies that seek to achieve the following:

1. Avoid permanent adverse impact on the natural state of the air, land and water;

2. Ensure a healthful indoor environmental quality;

3. Optimize social and economic benefits to the project and the community; and

4. Encourage occupant behavior, maintenance and operations that maximize conservation opportunities, reduce resource consumption and minimize wastes.

Fiscal analysis using life cycle cost estimating is part of a “reasonable payback” determination for energy efficiency and renewable energy technology. Approved life-cycle cost estimating measures to be used include first-cost, incentives, operating expenses, and utility savings for proposed technology. This policy shall implement renewable energy strategies that provide a payback of less than 10 years.

STANDARDS:

1. City owned, occupied or leased new construction and major renovation projects shall meet the requirements of the US Green Building Council (USGBC) Leadership in Energy and Environmental Design Program® (LEED®) for Silver level certification.

2. City owned, occupied or leased new construction and major renovation projects shall use 15 percent less total building energy consumption than the minimally code compliant building as modeled following the Title 24 requirements. Energy Pro software is the preferred software tool to identify efficiency.

3. City owned new construction and major renovation projects shall provide a minimum of 15 percent of total building energy from onsite self-generation using proven renewable energy technologies when site conditions and configuration allow for reasonable payback on the significant investment in renewable energy technologies.

4. City owned, occupied or leased new construction and facilities replacing plumbing fixtures shall use 20 percent less water than the baseline water consumption profile for interior non-process water uses.

5. City owned, occupied or leased facilities shall use non- potable water for permanent irrigation to the extent possible.

CRIME PREVENTION THROUGH ENVIRONMENTAL DESIGN: CONCEPTS AND MEASURES FOR USE IN DESIGNING PARKS AND COMMUNITY CENTERS

SDPD Neighborhood Policing Resource Team

October 2008 This paper defines the basic concepts of Crime Prevention through Environmental Design (CPTED) and presents guidelines for park design and operation. CPTED is based on a set of four design and usage concepts that can lead to a reduction in the incidence and fear of crime, and an improvement in the quality of life. These concepts are defined briefly as follows:

1. Surveillance. Involves the location and use of physical features, electrical and mechanical devices, activities, and people to maximize visibility in the environment. Creates a risk of detection for intruders and offenders, and a perception of safety for legitimate users.

2. Access control. Employs people, electrical and mechanical devices, and natural measures to create a perception of risk to offenders and deny them access to targets. Also guides legitimate users safely through the environment.

3. Territoriality. Uses physical features and signs to control activities in the environment. 4. Maintenance. Allows the continued use of the environment for its intended purposes.

Maintains the effectiveness of measures employed for surveillance, access control, and territoriality.

I. SURVEILLANCE These measures deal with the location and use of physical features, electrical and mechanical devices, activities, and people to maximize visibility in the environment. They create a risk of detection for intruders and offenders, and a perception of safety for legitimate users.

A. Outdoor lighting 1. Provide exterior lighting for visibility at night in parking lots, on

pedestrian paths, at building entrances and exits, etc. to enable people to see where they are going and identify others along their route. Light should be consistent to reduce contrast between shadows and illuminated areas.

2. Illuminate areas around buildings where persons might hide. 3. Avoid lighting isolated areas that people should not use at night. 4. Make sure that trees or other landscaping do not block light.

B. Outdoor sightlines

1. Maintain tree canopies at least 8 ft above the ground. 2. Keep shrubs trimmed to less than 3 ft except where higher plants would

not block any views, lighting, or camera coverage, or provide hiding places. For example, higher bushes or trees with lower canopies could be

APPENDIX F

F-2

planted next to a blank wall or the side of a building. 3. Grade land where practical without substantially altering the natural

terrain to provide unobstructed sightlines within the park and from adjacent streets and developed areas. Make sure that mounds and other terrain features do not create hiding places.

4. Use open landscaping and see-through fences instead of solid walls or hedges for boundaries where privacy or environmental noise mitigation is not needed.

5. Orient buildings for good visibility of the parking lots and other buildings in the park.

6. Orient parking spaces to provide good visibility between cars from the buildings.

7. Use open or see-through structures for exterior stairway and walkway railings, sitting areas, patios, parking spaces, etc.

8. Eliminate possible hiding or entrapment spots, e.g., dense shrubs, along pedestrian paths.

9. Install cameras or mirrors to provide visibility where sightlines are obstructed.

10. Use streets as buffers between parks and other land development where possible.

C. Outdoor facilities and activities

1. Install benches for people to sit and observe activities in the park. Plant trees to shade the benches.

2. Locate facilities for activities that attract large numbers of people in areas of otherwise low usage so users can provide surveillance of the area. These include basketball courts, ball fields, etc.

3. Locate facilities for activities that involve a few people at a time in areas of high usage and good visibility so they can benefit from the natural surveillance in the area. These include pay phones, bike racks, parking lots, hiking or jogging trails, etc.

4. Locate paths to and from buildings through areas that need surveillance. Use most direct route where possible.

D. Outdoor restrooms

1. Design interiors so that free-standing exterior privacy walls are not needed. Such walls can be used as hiding places and become entrapment spots. They also obstruct visibility of the entrances.

2. Locate entrances so they are visible from the main activity areas of the park.

E. Indoor facilities and activities

1. Locate activities that attract a large number of people where they can be supervised easily by park personnel.

APPENDIX F

F-3

2. Locate activities that involve a few people at a time in areas of high usage and good visibility so they can benefit from the natural surveillance already in the area. These include restrooms, elevators, stairs, pay phones, etc.

3. Locate restrooms along main corridors and not around corners or in alcoves.

4. Locate the office and front counter where personnel in it have a good view of the main building entrance.

5. Provide a clear view of room interiors from room entrances. 6. Keep hallways clear of display cases, etc.

F. Windows and doors

1. Provide two-way visibility in areas open to the public. Do not obstruct windows and doors with signs, displays, plants, etc.

2. Provide one-way visibility (from inside to outside) in areas not open to the public, e.g., with mirrored glass.

3. Install peepholes for viewing people seeking entrance to secure areas. 4. Install windows in corridor walls to enable room interiors to be seen from

the corridors.

G. Communications systems 1. Install emergency phones, alarms, or intercoms in convenient places for

people to use to report intruders or suspicious activities, or to call for help.

2. Post signs showing the locations of emergency communications systems.

H. Cameras 1. Install cameras to cover activity areas that cannot be seen by office

personnel. 2. Use video analytics or intelligent video software to monitor multiple

cameras for unusual or suspicious activity as it is occurring. The software will alert office personnel who have monitors, but would not be watching them all the time, that a parameter or alarm condition has occurred. These conditions can be set for day of the week and time of the day. They include the following: (1) motion in and out of an area, (2) non-motion, e.g., unattended package or illegal parking, (3) items that have moved or are missing, (4) behavior, e.g., casing vehicles in the parking lot or skateboarding, (5) numbers of people, vehicles, or other objects in the area, and (6) overcrowding, where numbers exceed a set threshold.

3. Have the cameras monitored off-site when the park is closed. 4. Call the police if a crime is observed. 5. Use cameras that provide high-quality, digital imagery of suspicious

persons and activities for use by the police in investigating crimes. Some cameras will start recording at a higher resolution when an alarm

APPENDIX F

F-4

condition occurs. II. ACCESS CONTROL These measures involve people, electrical and mechanical devices, and natural measures that create a perception of risk to offenders and deny them access to targets. They also help guide legitimate users safely through the environment.

A. Building security 1. Alarm all entrance and exit doors. Emergency exit doors should be self-

locking and designated for use only in emergencies. 2. Install motion detectors in all ground floor rooms with windows to the

outside. 3. Install a control panel in the office so personnel can see when any

entrance or exit door is open, and when any room is occupied. 4. Keep all supply and storage rooms locked. 5. Locate entrances in areas that are under surveillance or direct

supervision.

B. Walls, fences, and gates 1. Make walls and fences attractive as well as durable. 2. Use open fences, e.g., vertical wrought iron. They are preferred because

they are easier to see through, harder to climb, and less susceptible to graffiti. Fences and gates should be at least 6 feet high.

3. Use vines, thorny plants, and other landscaping along walls to make access more difficult for graffiti vandals.

4. Install gates or bollards at parking lot entrances to prevent vehicles from entering the lots at night when the park is closed.

5. Install shields on gates to prevent persons on the outside from inserting a hand or tool to turn handles or knobs, push in a latch, or pull against a push bar to open the gate.

6. Use padlocks with shielded shackles that cannot be cut with bolt cutters.

C. Restraints 1. Install barriers or other devices to prevent misuse of park facilities or

areas, e.g., bathing in fountains, camping overnight, or violating protected open space.

2. Design public amenities to discourage misuse, e.g., shape benches to be comfortable for sitting but not for sleeping.

3. Roughen smooth surfaces and ramps in front of benches, planter boxes, low walls, steps, and railings to discourage skateboarding. Other design measures include: (1) pavement cutouts instead of planter boxes for trees, (2) shaped edges on tops of seat benches and low walls, (3) small metal or plastic discs or strips on the edges of existing benches, planter

APPENDIX F

F-5

boxes, and other flat surfaces that skateboarders abuse, (4) small metal discs or bolt heads on tops of existing railings, (5) height variations, arm rests, or seat dividers on the tops of seating surfaces, (6) breaks, bumps, or height variations on low walls, curbs, railings, and planter boxes, and (7) circular picnic tables and curved benches instead of rectangular tables and benches on concrete paving.

4. Close areas and paths when adequate lighting and surveillance cannot be provided. Post signs to indicate closures times.

III. TERRITORIALITY Territoriality measures involve the use physical features and signs to control the use of the park and promote neighborhood pride in it.

A. Boundaries 1. Define clear boundaries between areas that are open to the public and

those that are limited to park personnel only. Signs, walls, fences, doors, gates, landscaping, etc. can be used for this.

2. Establish boundaries to prevent conflicts between different groups, e.g., teens and seniors, so all user groups will be able to enjoy the park.

B. Signs

1. Make signs legible and unambiguous. Use symbol signs where possible. 2. Locate signs in strategic places. 3. Use signs to: (1) discourage access to dangerous areas, (2) indicate

opening and closing times, (3) display park regulations, (4) direct people to safe paths, exits, emergency assistance, means of calling for help, etc., and (5) inform people how to report maintenance problems.

IV. MAINTENANCE Maintenance measures permit continued use of the park. They help maintain the effectiveness of the measures employed for surveillance, access control, and territoriality.

A. Low-maintenance landscaping 1. Use low-maintenance designs and irrigation systems, and drought-

resistant plants to facilitate upkeep over time. 2. Avoid use of loose rocks, bark, etc.

B. Hardening against vandalism

1. Employ design features and materials that cannot easily be vandalized, stolen or used to damage the property.

2. Use graffiti-resistant paint or anti-graffiti coatings on walls, benches, light poles, signs, etc.

APPENDIX F

F-6

3. Avoid blank facades at ground level. 4. Use screens, wired glass, or other protection for light fixtures, bulbs, and

cameras. 5. Use shiny aluminum or shatter-resistant glass for mirrors.

C. Securing backflow preventers

1. Paint the device. Paint is a deterrent because painted metal is less valuable.

2. Camouflage the device. Fake rocks work well. Just make sure there is a one-foot clearance around the device.

3. Hide the device. Paint it green and place it in a bush or hedge. This is a low-cost measure.

4. Use a device with plastic parts. Plastic is less valuable. 5. Enclose the device in a protective cage or box. Must mount it securely to

the ground and use a tamper-proof lock or else the thieves will steal the cage too.

6. Install a locking-cable system with shielded-shackle locks and a concrete foundation.

D. Securing utilities

1. Locate electrical and telephone system controls inside the building.

2. Lock any exterior electrical or telephone system components in a sturdy box with a shielded padlock.

TRAIL POLICIES AND STANDARDS

OPEN SPACE DIVISION

October 4, 2010

1. INTRODUCTION

To identify and quantify trail standards, a basic classification based on existing use, projected use, and demographics specific to the area must be identified. Trail use, alignment, and classification will be consistent with Community Plans and other guiding documents. While most of the existing trails provide loops, and local destinations within the specific park units, many of these trails are within Open Space canyons that extend easterly to westerly. The majority of these Open Space canyons are currently managed by Park and Recreation staff. Many of these east / west canyons provide not only recreational hiking, biking, and equestrian trails, but commuter routes that are used by local residents. Additionally, many of the smaller Open Space canyons that are not under the direct management of designated Open Space units, have existing trails or paths that provide pedestrian and bicycle access to other parts of the City and the larger Open Space Regional Parks. Trails within the City managed lands will range from “primitive” (narrow, marginally improved) trails, to “improved” (wide, varying degree of improvements). The majority of the trails are existing use patterns and any improvements to match the trail classification will be implemented to improve safety, sustainability, and provide for protection of natural and cultural resources.

2. TRAIL CRITERIA

2.1 TRAIL DEFINITIONS

To be an approved/official trail, the trail must meet one or more of the following basic trail definitions:

2.1.1 Destination Trail: A trail designed to go to a specific destination. The destination may be a point of interest for scenic, educational, or activity-based purposes. The trail destination will usually include interpretive signage or other information.

2.1.2 Journey Trail: A trail that provides a route to pass through and enjoy natural areas without having a specific destination other than the trail itself.

2.1.3 Loop Trail: A single trail that provides a loop. This type of trail will usually have scenic or other characteristics, but may also be a short exercise trail.

2.1.4 Connector Trail: A trail that connects or links to another trail or trail system. This type of trail could also be part of a larger destination, journey, or loop trail, or may be the start or ending of an alternate transportation route.

APPENDIX K

K-3

Even if a trail comports with one of the above definitions, a trail will not be approved if it is redundant or if it serves only a single private property. For example, a destination trail for which the trail itself is the only destination may be redundant with another trail in the same canyon complex. Other reasons for not approving/accepting a trail into an approved plan include lack of legal public access, avoidance of environmentally sensitive areas, or other limiting factors.

2.2 TRAIL CONDITION CRITERIA

In addition to needing to meet one of the above definitions, the following Condition Criteria are also required:

2.2.1 Safety: Trail conditions that do not present undue hazard to users. New trails will be designed and constructed to provide for safe use. For existing trails, identification and repair of identified hazards must be resolved using Best Management Practices (BMP) of trail, and trail structure construction.

2.2.2 Sustainability: New trails must be capable of being constructed and maintained in a self-sustaining manner (within reason) under adverse conditions. Existing trails must be improved to the highest level of sustainability using Best Management Practices except as described below. Water management and user management are critical components. Trails improved to the highest level of sustainability are also safe trails.

2.2.3 Non-compliant Trails: One assumption is that yet-to-be constructed, planned trails can and will be built in a safe and sustainable manner. A second assumption is that a number of existing trails require improvements (re-engineered, reconstructed or realigned) in order to become sustainable. Finally, some existing trails are not sustainable and cannot be re-engineered, reconstructed or realigned because of access or landform limitations. In this case some trails will be closed and some will be given extraordinary efforts towards retrofitting for improved but not total sustainability, as long as they are safe. Trails will be chosen for this extraordinary level of effort only if the trail meets multiple Basic Trail Definitions and is highly used by the public.

2.3 TRAIL CLASSIFICATIONS

2.3.1 Primitive Trails: These trails will vary in width, with a minimum trail base width of 48 inches. Actual used trail width may be less than this base. Minimum base is to accommodate maintenance needs, bi-directional travel, and provide safe passing space. These are trails that see limited use, are usually more difficult, with grades that may exceed trail standards, and are primarily for recreational users.

2.3.2 Moderate Use Trails: These trails will have a minimum trail base width of 60 inches. These trails may be multi-use, are destination-, journey, loop, or connector trails. These trails are usually less difficult with moderate grades (some exceeding trail standards), and usually will see multiple direction travel. Trail engineering and tread improvements

APPENDIX K

K-4

may include surfacing amendments, and structures for resource protection and visitor safety.

2.3.3 Utility Access Paths, Park Management and High-Use Recreational Trails: These trails are usually existing service roads that provide recreational trail corridors. These are normally destination-oriented, or connector trails. Most of these trails/roads provide access for park management staff (Park Rangers), and emergency response. Additionally, many of these trails/roads were originally constructed for utility access and maintenance (Public Utilities, SDG&E), and are still active for these uses. Width of these trails/roads will be no less than 8 feet, and will average 12 to 14 feet. Tread surface is usually graded annually by utility companies, with minor repairs and improvements made by Park staff (as needed). As these trails/roads are usually linear to the orientation of the Park, many local residents use these routes as commutes to and from work. Tread surfaces may be improved with the installation of surfacing material to reduce erosion, and provide for trail sustainability.

2.3.4 Circulation Trails: These trails are usually associated with transportation corridors, and are often incorporated into new developments. They vary in width from 8 – 14 feet, and normally have improved trail surfacing. Many of these trails that are adjacent to high automobile traffic areas will be separated from traffic flow by fencing or other barriers. Grades on these trails will generally be gentle; however trails adjacent to roads may exceed normal trail standards and be consistent with maximum allowable road grades.

3. TRAIL CONSTRUCTION STANDARDS

3.1 GENERAL

The majority of new trails within the City of San Diego are associated with new development. Many of the new housing development projects, as well as commercial developments, have a trail component. While most of these new developments have an integrated “internal” trail system, consisting of all levels of paths and trails (including sidewalks), they normally include trail connections to other existing trails and trail systems. The connection of new trails to existing City trails and trail systems will need to be approved by the Park and Recreation Department Open Space Division, and must be constructed to minimal City standards. These standards will reflect maximum user compatibility, safety, and resource protection. An initial premise in trail design shall be a design that facilitates multiple users. During the design process, site-specific characteristics (e.g., grade, site distance) may require a design that precludes certain user groups. Park and Recreation staff may close trails to certain user groups for safety purposes if post-construction usage is not safe. Additionally, as these trails will ultimately come under the jurisdiction of the City, it is important that they are constructed to the highest standards to minimize maintenance needs, protect and preserve sensitive natural and cultural resources, and provide for safe and enjoyable use.

APPENDIX K

K-5

New trails proposed to be constructed by the City of San Diego are usually associated with improving connections to existing trails and facilities, as well as to other trail systems. These new trails may be built “in house” by City Park and Recreation staff, or contracted out. In all cases, new trails will be constructed to City standards, and will be built to “Barrier Free” or ADA standards wherever possible.

Alignment of new trails (including trail realignments) will be to provide a route selection that is both safe and sustainable. Impacts to sensitive habitat should be avoided unless long-term sustainability requires impacting sensitive resources that will ultimately enhance long range resource protection and preservation. Additionally, if points of interest occur near trail alignments, it may be advisable to include these points of interest as trail amenities. Stream crossings, overlooks, and other locations should be considered for inclusion to the proposed trail to prevent unauthorized trail cutting to enjoy these locations. New trail alignments or trail realignments will comply with all local, State (CEQA), and Federal regulations and requirements.

All new trails must be consistent with General, Community, and Specific Plans, and meet all regulatory requirements.

3.2 BARRIER FREE TRAIL DESIGN AND ADA RECOMMENDATIONS

The following guidelines apply to new trail construction required to be accessible and to modifications to existing trails required to be accessible. See Draft Final Accessibility Guidelines for Outdoor Developed Areas. These are pending recommendations (“Proposed Guidelines” / ADAAG) that have not been adopted. City standards will reflect the final ruling when adopted.

New trail construction requires that all new trails are built to City Park and Recreation standards, and will be constructed to address issues of accessibility in accordance with local, state and federal law. While the City Trail Standards reflect the minimum construction requirements, specific conditions may be modified by agreement with the City of San Diego Park and Recreation Department Open Space Division.

Trails to be constructed as part of new developments, and connected to other existing trails or destinations will be built to ADA recommendations in accordance with local, state and federal law. All proposed trails associated with new development must be approved by the Park and Recreation Department’s Open Space Division, and constructed according to approved plans. New trails that will not meet ADA recommendations will have an ADA component as part of the trail system in accordance with local, state, and federal law (viewing area, rest area, interpretive location). Access to all ADA compliant facilities shall be constructed to City standards.

3.3.3 Tread Width: o Primitive/Light use: Minimum constructed tread width of 48 inches o Moderate use: Minimum constructed tread width of 60 inches o High Use and Utility Access/Park Maintenance Paths that also serve as Trails:

Minimum constructed tread width of 96 inches o Trails in MHPA: Trails in core areas or wildlife corridors of the Multi-Habitat

Planning Area (MHPA) the maintained trail tread will not exceed 48 inches in width.

Note: Generally, all trails should be brushed 1 to 2 feet beyond the trail tread. In the MHPA, where paths may not exceed 48 inches in width, brushing shall be limited to the 48 inch trail corridor.

3.3.4 Vertical Clearance: o 120 inches for equestrians o 80 inches minimum for hikers and bicyclists

3.3.5 Surfacing: o If required/desirable based on site conditions (i.e. soil type, designated and type of

3.3.6 Elevation Changes:

o Elevation changes will use climbing turns where possible. If switchbacks are used, running lengths should be as long as possible. Steps shall conform to step calculation standards.

3.4 ACCESS POINTS AND TRAILHEADS

All access to City owned Open Space will be from City owned land and public facilities or public access easement, and will provide access for all public users where appropriate. Trail use designation will reflect access point requirements. While most access points will be designated for limited shared use (mountain bikes / hikers), many will need to accommodate equestrians as well. Equestrian staging facilities will need to accommodate horse trailers, and sufficient area for ride preparation. Access points in many of the urban canyon areas will be from public streets, City parks, and other City owned and managed lands. Access from major Open Space Parklands is from identified staging areas, and recognized trailheads as identified in Park Master Plans and/or Park Natural Resource Management Plans, and Community Plans. As new developments adjoining these Open Space lands are completed, additional trailhead opportunities will be identified.

Access points to trail systems in both urban canyons and larger Open Space Regional Parks and developed parklands should be limited to specific points that provide safe and sustainable trail entry points. While many areas have well used access points from local communities, these

APPENDIX K

K-8

entry points should not be excessive. General requirements should limit trailheads to no closer than 0.25 miles. Some communities may have multiple access points within shorter distances to accommodate uses beyond recreational trail use. Connections to local schools, shopping, and alternate transportation uses may allow for spacing less than 0.25 mile. These closely spaced access points will need to be evaluated for criteria including; safety, sustainability, user volume, demographics, and justification of community needs. In some areas it may not be feasible to provide access at 0.25 mile intervals. Due to steep topography, sensitive habitat, dense vegetation, and private property issues, access points may exceed several miles. It is the goal of the Park and Recreation Department to provide the most reasonable, rational, and safe access to trails in Open Space.

The following items are basic guidelines for access locations. In many, deviation from these guidelines will require site specific evaluation for rationalization, and inclusion as approved trailheads.

o Access from identified trailheads and staging areas in Open Space parks o Public access from streets, City parks, and other City owned lands o Minimum 0.25 mile spacing (site specific) o Safe / sustainable access (per trail standards) o Reasonable access to existing trail system o Specific use (recreation, alternate transportation, other) o Recognized in Community or Park Master Plans o New access to accommodate new trails in developing City areas o Reasonable access for park staff to maintain and patrol as needed o Appropriate signage

Additionally, efforts should be made to provide the highest level of access, including ADA components, at trailhead locations. As most City trailheads and access points normally drop into steep canyon areas that do not provide ADA opportunities (landform, vegetation, etc.), it is important to try to provide a reasonable trail experience for disabled users. These ADA trail components may be loop trails, or scenic overlook opportunities.

4. TRAIL CONSTRUCTION TECHNIQUES AND FEATURES

4.1 GENERAL/HISTORY

Existing trails that are currently managed by the City of San Diego were developed utilizing a combination of service roads, easements, game trails, and trails created by casual use (volunteer or social trails). These trails existed at the time of acquisition of those properties (for park and Open Space preservation) and, although many of these trails do not meet current trail standards, they became the core of the City’s trail network. Over the last decade, Park Ranger staff, assisted by large numbers of volunteers and multiple funding sources, has, and continues to, successfully justify use of and improve those existing conditions to meet the safe and sustainable goals. The ultimate goal is the implementation of an organized trail system more in keeping with “Best Management Practices” consistent with National Park Service and

APPENDIX K

K-9

California Department of Parks and Recreation guidelines. In working toward this goal, the City is striving toward the improvement of these trails during routine maintenance, and will work toward “barrier free” trails wherever possible. Many of the existing trail alignments may not be favorable to total accessibility; however, ADA and Barrier Free construction will be implemented as opportunities allow.

Existing trails within both managed and unmanaged City lands vary. Trails may have evolved from game trails or casual use (narrow, single-track), or shared road or utility access (wide, 8 – 14 feet). These trails are usually accepted by the local community, and often as part of the community approved plans, as “the trail system”. These trails may be in any condition, from poor to excellent, depending on level of maintenance. Level of maintenance is usually dictated by safety, resource protection, and public need.

Classification of existing trails is determined by the City of San Diego, Park and Recreation Department’s Open Space Division, or sometimes by General or Community Plans, and community input. As use and demographics change in many locations, it is important to evaluate use designations, and change if necessary. As trails become a larger part of overall transportation within the City, as well as for recreational enjoyment, it is important to provide rational classifications and linkages to other transportation corridors and routes. Trails may provide for important alternate transportation (commuters), or casual interconnection within communities (schools, shopping, parks). As conditions change in many of our Open Space areas, either by increased use or level of connectivity, many trails will need to be modified to a higher level of accessibility. While these trails may become more and more important as alternate transportation, it is important to maintain the integrity of the natural landscape and to preserve and protect sensitive natural and cultural resources.

Trail standards for both new trails and existing trails may need to be modified for specific locations. Topography, soil types, vegetative cover, and adjacent development may affect design criteria. All trail alignments, or trail reconstruction must be approved by the Park and Recreation Department’s Open Space Division.

A number of agencies including California State Parks, the National Forest Service, Bureau of Land Management (BLM) have developed “Trail Standards” that are consistent for their particular agency. However, many of these standards are not always effective in the Southern California region. Some of the major problems associated with specific regional conditions may require more inventive techniques in restoring and maintaining trail tread.

California State Parks has compiled one of the more comprehensive sets of standards and design guidelines in their “Trail Maintenance and Management” manual. While these standards and design criteria are considered the most applicable to this region, some modifications may apply to specific locations. Specifics addressed in this section use the California State Parks manual as baseline criteria. Soil types, vegetative cover, and precipitation in many areas of Southern California have considerably different characteristics than other areas within the State.

APPENDIX K

K-10

4.2 ACCESS PATHS AND TRAILS (UTILITY ACCESS AND EASEMENTS)

Throughout the Open Space lands within the City of San Diego, there are existing access paths and easements for utility service (Public Utilities Department, SDG&E, etc.). Many of these access paths have been adopted by the community as trails. In many cases these paths provide reasonable trail connections and linkages. As these paths are normally linear and bisect Open Space boundaries, they may provide excellent connections between developed areas of the City.

Whenever possible, and where conditions are favorable, improving these access paths to trail standards may be advised. Grade and out-slope for these paths should remain consistent with trail standards; however, width may need to be modified to accommodate utility service equipment. It may be advisable to improve surfacing to reduce wear patterns and minimize erosion. In most cases, minor modifications to tread design will reduce or eliminate significant erosion concerns.

Many access paths are sited in or near canyon bottoms. These locations must be addressed to eliminate erosion and siltation problems. Substantial siltation could potentially affect both seasonal and year-round water flows. Specific modifications to tread design, tread surfacing, specific erosion controls built into the path, and planting with native vegetation may be implemented to alleviate erosion. Additionally, many of these access paths/trails may be important for Park and Recreation, to provide access for Ranger patrols, maintenance, and emergency response. In cases where the need to maintain these trails for Park and Recreation use is identified, the width should be no less than 8 feet. In cases where Park and Recreation access is not required, it may be advisable to reduce the trail width through revegetation while still allowing occasional maintenance vehicle access. Decisions as to ultimate use and needs should be consistent with all regulatory requirements, community plans and other guiding documents, and meet the identified needs of all involved agencies and departments. Developing and modifying access paths to a shared-use may allow for the elimination of other trails or impacts to the land.

As many of the access paths located in Open Space areas may cross, or be located near, water courses it may be necessary to construct facilities to provide for long-term maintenance and public use. Improved facilities to be constructed may include bridges, retaining walls, BMPs, drainage and erosion controls, or other appropriate facilities. If these facilities are expected to be used by heavy equipment, appropriate design and engineering standards consistent with trail standards must be implemented. Engineering design standards are current California State Park approved standards, and are consistent to trail design standards. If paths/trails are to be used by multiple use-groups (disabled, equestrian, etc.) specific design criteria is required. Specific data as to construction standards is on file with the Park and Recreation Department’s Open Space Division.

APPENDIX K

K-11

4.3 CONSTRUCTION ROADS TO TRAILS

Roads often need to be constructed in Open Space areas for maintenance or construction purposes. In many cases these roads are constructed for limited use during the duration of a specific project, and then will be utilized as a trail or as access for patrolling by ranger vehicles

Roads constructed in Open Space areas that will ultimately be used as trails need to be built to the same standards as trails. The only modification would be to the degree of out-slope (tilt away from uphill bank). Because of moderate use by medium to heavy equipment, it is often necessary to increase the “angle of out-slope” to compensate for compaction and general wear patterns. This out-slope will eventually settle into a slope more consistent to current trail standards. Careful assessment of soil types is important when designing road out-slope. If soil types are high in certain clays, excessive out-slope may create sliding hazards for heavy equipment. If these soil conditions are present, then a lesser degree of out-slope, or short in-sloping may be recommended. Degree of out-slope must also take into consideration, grade (or pitch) of road, anticipated water loads, and ability of the landform to naturally moderate water flow. Many areas experience rainfall events that are extreme, and may not show in normal data recording formats. Exceptional events that drop excessive amounts of rain within a short period of time may not show in standard records, and it becomes important to look for indications of these events. Also, information that can be obtained locally (park staff, local residents, etc.) may be valuable to determine the occurrence of extreme events.

Moderating flows at water crossings (gullies, ephemeral streams, etc.) should also use methods consistent to trail construction standards and practices. Increasing out-slope at approaches and at minor crossing is advised. Armoring these crossings may also be advised. Major crossings or ephemeral streams also may need increased out-sloping. Additionally, the “upstream” portion of this drainage may need erosion controls to moderate water flow impacts. Stacked “rubble” rock walls will moderate water energy, but still allow for flow. These walls should be constructed as shallow “U” shapes with the apex being toward the downstream side. Smaller crossings may also use this type of control. It may also be advised to install crushed rock as road base to allow drainage.

Climbing turns (resembling switchbacks) used to reduce grades need to be addressed as similar types of turns used in trail construction. At turns where water loads would impact the lower section of road using out-sloping, the profile of the road should be modified to an in-slope on the upper leg as the road approaches the turn. Water loads should then be directed away from the road at the apex of the turn. Selection of where the transition from out-slope to in-slope on the upper leg of the road will depend on site specific conditions. Outfall drains at the turns may need additional erosion controls to prevent erosion.

Roads graded for construction usually will be in excess of trail standards. If material is available, clear soil may be backfilled on the uphill side of the road to reduce width. Normally, time will reduce width with sloughing, and soils carried in water transport during rain periods, and the road will naturally narrow. If there are no constraints, trimming the downhill bank of the road may also be done to reduce width.

APPENDIX K

K-12

4.4 EROSION CONTROL TECHNIQUES

Soils in the San Diego region can be highly susceptible to erosion. Because of the sensitive nature of many areas, the addition of chemical amendments to the trail tread may not be advised. For modifications to existing trails, changes in degree of trail tread sloping, number of changes in sloping due to lack of cover (i.e.: watershed capacity), and drainage outfalls at switchbacks and climbing turns may be required. Additionally, while it is traditionally unadvisable to add organics to the trail tread, the use of cuttings from brush clearing or thinning to rebuild tread can be implemented in some cases.

Erosion controls for all areas should be consistent. This is especially important with trails, roads, and access paths. A basic understanding of what creates the greatest conditions for erosion is important. Two important factors remain consistent: Water Volume + Water Velocity = Erosion. If controls are constructed to break water flows, erosion will be minimized. Changes in slope or direction of travel will reduce velocities. Multiple controls will reduce both velocity and volume.

By looking at the surrounding landforms, it is necessary to identify how water moves across the land. If the trail / road / path intersects the normal flows, it is important to design (or re-design) these facilities to allow water to move in a fashion as close to nature as possible. With the exception of established watercourses, gullies, and other definitive water channels, water will normally “sheet flow” across the land. It is important to re-establish this “sheet flow” when designing or re-engineering trails / roads / paths. By designing trails with consistent out-slopes, water will shed off the trail in low volumes and velocities. If the landform itself is intact, the ability to absorb this water is increased.

Many of the trails and roads currently accepted as part of the City trail inventory consist of old scars that run down the fall line of slopes. Many of these sites are severely entrenched, and it may be difficult to direct water flows to sheet. In these and other extreme cases, “short water management” (managing water within short distances) is advised.

In areas where redirection to the sheet-flow concept is not feasible, the construction of silt dams, retaining walls, and well designed drains will moderate water flow is advised. On trails and roads that have long pitches where water cannot be redirected, a variety of options may be implemented. These include:

o Periodic water diversions and drains. These drains may provide an escape for redirected water, or may be designed as silt basins to capture transported material as water slows. These capture basins require maintenance to redistribute captured material and remain effective.

o Multiple cross slope changes. It is possible to change the cross slope of the trail or road, multiple times within short distances (20 – 50 feet). At each change water will slow and some transported material will fall out. Over a period of time, with maintenance as needed, this can potentially re-establish the topographic profile.

APPENDIX K

K-13

Multiple changes in direction increase length and reduce grade. Careful selection of trail direction changes may provide opportunities to augment erosion controls. Extreme care should be used to assure that water does not flow down the trail.

o Drain Dips. Drain dips and drain lenses can be constructed in areas where it may be effective to channel and redirect larger water flows. While these are very effective in managing water flow, it is important to reduce volumes and velocities as much as possible prior to drains.

o Swales and Culverts. These should be a “last resort” method of controlling water flows. Swales capture large volumes of water and channel them to a specific outfall. This increases volume and velocity, and may present a serious problem when dealing with unloading captured water. Swales are also normally rock lined. This rock will slow water sufficiently to allow transported material to fall out. If swales are not maintained, this material will block the swale and redirect water flow to paths of least resistance. Culverts are also problematic for the same reasons, with the additional problem of dealing with excessive water energy generated at the outfall.

o Silt Dams. May be constructed of rock, earthen, or straw waddles. In constructing large area silt dams, it is important to configure dam alignment to be effective. In general, dams should be constructed in a downhill “horseshoe” alignment, with the apex of the curve the desired flow pattern. By reconfiguring these dams during construction and maintenance, it is possible to stabilize large surface areas.

Many areas that have been designated as trails may be old scars from previous disturbance. Firebreaks, easement corridors, old grading scars that have expanded over time, and fire damaged areas may present large surface areas that are prone to erosion. If these areas have been accepted as trails it is important to stabilize the entire affected area as soon as feasible. The establishment of a trail within this disturbed corridor should meander as much as possible. In trail sections where there has been considerable erosion, and soil types are sandy or non-binding, the laying-in of alternating layers of vegetation mats (from cuttings), and soil has proven effective. Installation should consist of alternate layers of 4”- 10” cuttings covered with 12”- 16” soil, and thoroughly packed. Trail cap should be no less than 12” of soil. Properly implemented, this layering will stabilize soil migration and enhance bonding of soils as organic material breaks down. Settling of tread will occur as organics degrade, and periodic rebuilding may be required until tread stabilizes.

In some areas where soil migration (primarily sand) is a problem, native soils high in clay content may be added. The addition of inexpensive cat litter to sandy conditions has also been successful in stabilizing soil migration. Areas of high erosion may also require more aggressive trail out-sloping, or multiple changes in trail slope within short distances.

In-sloping and out-sloping of trails in areas susceptible to high erosion may have to be more aggressive to sheet water off the trail surface quickly. Additionally, in areas where consistent

APPENDIX K

K-14

sloping is not possible, multiple changes in slope within shorter distances may be necessary to move water off the trail tread (rolling slope). Special care should be taken to assure water outfalls (drains) are well armored and disperse water quickly. Focused water at drainage outfalls will cause rapid erosion.

Natural and manufactured polymer binders, soil cement, and clay amendments have been successfully implemented to stabilize and harden trail surfaces.

The use of water bars is not advised in areas where serious erosion is a problem (both trail and surrounding area). Water bars tend to clog rapidly or be affected by serious down-cutting at the outfall. Construction of “drain dips” at water-bar locations is an effective control to break and disperse water flow. If water bars are to be used until the trail surface can be properly engineered, multiple, closely spaced bars may be needed to control flow. These water-bars should be used as a temporary measure only.

4.5 TRAIL TREAD SURFACING MATERIAL

Trail tread surfacing can range from unimproved natural soils to hardened / stabilized material. It is important to remember that the trail is to be an integral part of the natural landform, and should not substantially change natural landform characteristics. The ability of the trail tread to allow some water percolation into the watershed is also important.

Trail surfacing material may be needed for high use, improved accessibility (ADA), specific user groups (bikes, equestrians, etc.), or to reduce or eliminate erosion. Various grades of DG (decomposed granite) are often used; however, a Class II, or Type II road base is preferable (no recycled material). DG may be used if it is well graded and the color is consistent with surrounding landforms. These materials are made of graded material, from very fine to coarse, and tend to lock and bind better than single grade aggregate materials. If Class II road base or DG is properly compacted the tread will remain sustainable even at grades exceeding trail standards (providing all other trail criteria are consistent to standards). With proper out-sloping, in-sloping, and slope reversals (rolling grade), a compacted Class II base trail tread will remain sustainable under high use and moderate to heavy rain events.

Often, trails may see very high-use by multiple user groups. Circulation trails and some high-use Recreation trails may need a soil stabilizer to bind the tread surfacing. Soil stabilizers can include, natural or chemical polymer binders, soil cement (Green Book), clay, lime or salts. Some of these stabilizing treatments may not be compatible with sensitive natural resources, and careful analysis of an additive must be assessed before installation.

4.6 TRAIL GRADES

Range of trail grades are affected by trail type and projected use, soil types, and general landform characteristics. Generally, some amount of grade should be considered for all trails to reduce erosion by enhancing water movement and management. See Guidelines for new trails and modifications to existing trails section for grade guidelines.

APPENDIX K

K-15

Classification of trail type, and expected user group may allow some latitude in determining grade. While bikers (and some hikers) may find grades exceeding 12.5% difficult, equestrians my find grades up to and beyond 25% as acceptable. Additionally, classification of trails (primitive), and designated user group (equestrian, difficult hike, technical bike) may be critical factors on determining grade.

New trails in the City of San Diego should be aligned at the recommended grade range of 2% - 12.5%. Any grades exceeding 12.5% must be approved by City staff trained in trail design and engineering to assure safe and sustainable alignment. While long-term sustainability is crucial, visitor safety must be maintained.

4.7 SWITCHBACKS AND CLIMBING TURNS

While switchbacks are not advisable when designing a trail with rapid changes in elevation, many existing trails do utilize this design. Because it is often impossible to redesign these trail sections, special care must be taken to manage these turns. If possible, redesign of turns, to more geographically friendly climbing turns, is preferable.

Careful assessment of switchback alignment is important in this region. Because of heavy rainfall events and the potential for serious erosion, water management on the trail tread is critical. Changes from out-slope to in-slope when approaching turns must be assessed to determine proper location. The transition zone (from out to in) will often act as a water bar when water flow is heavy. Care in selecting a location where water drains from this point must take into consideration the ability of the surrounding landforms to handle substantial water flows. Selecting areas with heavy vegetative cover or rocky, broken surfaces (to break water energy) will help minimize erosion at these points.

Outfalls, or drains at the apex of turns must also be critically assessed. Often, these turns will still dump water to the segment of trail below. This may mean that the in-sloped leg of trail in this section must be shortened to minimize water loads. Additionally, drainage design must effectively break water energy rapidly and disperse water before the next trail leg. A “Herringbone” design of small water bars may help direct water flow from channeling at the drain. If erosion channeling is already evident, a series of retaining walls may be used to break water flow and drop out transported soil. This will also help to rebuild the erosion channel.

Other problems commonly associated with trails utilizing multiple switchbacks and even climbing turns, are hikers cutting the trail. Due to the sensitive nature of regional vegetation, cover is lost quickly in these sections, and the ability of the landform to moderate water is compromised. In areas affected by serious cross traffic, erosion often becomes a major problem, and may affect the out-slope design. Substantial retaining wall construction may be needed to not only keep visitors “on-trail” in these areas, but to break water flow. Additional retaining walls may need to be built within these sections to moderate both human use and water flow. Rock construction is preferable, as some water will still pass through structure, but slowing flow enough to drop out transported material. Rubble type walls are effective in the

APPENDIX K

K-16

interior of these cuts as well. In extreme cases, where cut-across areas are extensive, other barriers may be necessary (fencing, signage, etc).

Whenever possible, trail design to deal with moderate to severe elevation changes should use climbing turns instead of switchbacks. In many locations, topography may allow for some realignment of existing switchbacks to climbing turn configurations.

4.8 STEPS AND STAIRS

If elevation changes are too steep to construct trail within grade standards, steps or stairs may need to be considered to make the elevation transition. There are several types of these facilities that can be installed. Step configurations may be full-cribbed, partial-cribbed, cut-out stringer, un-cribbed (free-standing), and cable steps. With the exception of cable steps, all of these structures can be constructed of either wood, rock, or appropriate recycled material. Due to severe erosion many trail alignments have degraded to the point where steps are required for safety, as well as stabilization and protection of natural resources. Steps or stairs may be advised in some new trail construction to prevent degradation of landform, and visitor safety.

Steps must be constructed to engineering standards wherever possible (rise and run). If the site will not accommodate standard construction, step modifications may be acceptable upon inspection. Longer runs, or landings, are typically constructed for trails that may be used by horses, or in areas where long grades exceed advised step, run limits. Changes in design must be approved by the City Park and Recreation Department Open Space Division staff before installation. The addition of transitional landings within the step carriage may be constructed to accommodate excessive length of runs, and to break change in dissimilar landing designs. The most important factor is to provide uniform rise and run throughout step alignments.

Prior to construction of steps, the site must be surveyed to determine structure configuration. This is done by calculating the rise and run of the site. Rise will be the total elevation gain (vertical distance) to be achieved. Run is the total horizontal distance to make this elevation change. Average acceptable rise standards are 7” – 9”. Acceptable length of runs (or landings) is 13” – 18”. To calculate needs, divide the total vertical rise by 7” or 8”. This will determine the number of rises within the alignment. Subtract 1 from this number for the number of landings. Divide this number into the total length (horizontal distance). These are your runs (landings). If possible, adjust the total run length to conform to run standards.

4.9 BRIDGES & PUNCHEONS

The majority of water flow in the region tends to be ephemeral; however, as the region continues to develop, much of this seasonal flow has changed to “year-round” flow due to increased irrigation and hard surface runoff. Because the type of rainfall experienced in this region often tends towards heavy rain events of short duration, the water flow can be extreme at times.

APPENDIX K

K-17

Site assessment of location for bridges or puncheons must be carefully considered to determine suitability of construction. If locations for this type of construction (puncheons particularly) are being considered, it is important to look at flood event history at the site. Careful assessment of the watershed and the potential for high-energy water flows may make use of structures inadvisable. The construction of Arizona style or ford crossings is preferred in these areas.

If puncheons are to be built, assessment of end member (mud sill) placement is important. Bank integrity, stream channel geography or alignment, or potential for migration of flow during large events, must receive careful consideration. If the site location appears to be fairly stable, and flood, or flow, history indicates the location does not experience much alteration, puncheons may be constructed. Anchoring one end of the structure may be done to secure the structure in extreme events. This will allow the puncheon some flexibility as it will swing away during these events, and can be relocated afterward.

Bridge construction in the region requires similar assessment as puncheons, however most bridge locations are normally in relatively stable flow areas. As local geologic conditions vary considerably in the region, assessment of bridge foundation is important. Soil types or integrity of geologic structure for bridge footings may be questionable. In these areas the use of pilings for primary bridge support may be advised. Due to high erosion potential, bridge foundations and approaches may be compromised over time and not provide effective support. There are a variety of bridge configurations and material types that will address specific crossing needs and environmental constraints.

4.10 DRAINAGE

Due to the nature of regional rainfall, trail structure, and soil types, drainage concerns may require more extreme methods to manage water flow and minimize erosion. As previously stated, the arid nature of the region (sparse vegetation), violent rainfall events, and highly erosive soils requires careful “site specific” assessment when constructing drains.

Erosion is the primary cause of trail damage. Water volume + water velocity = water energy (i.e.: erosion). As water moves down the trail and increases in energy, it erodes material from the trail. As more material is added to the moving water, it becomes more effective at cutting more resistant materials. The longer and faster the water moves down the trail, the more erosion. By slowing and/or effectively diverting the water, the erosion process can be controlled.

Drainage on trails in this region is best accomplished with well designed “out-sloping” or “in-sloping” (at turns). State Park guidelines advise tread slope from 2% to 10%. This guideline is effective in new trail design, and long-term maintenance level tread surfaces, however higher percent grade may be required in some areas. Trails that have extreme pitches (grades), and suffer from high-energy water flow may require a more aggressive out-sloping to manage water flows. Installation of drain lenses, or large-area drain-dips may allow for reducing out-slope. Some trails may require out-sloping in excess of 15%-18% to stabilize tread and manage water flow. Extreme cross-slopes are normally associated with short-term stabilization, and should be

APPENDIX K

K-18

modified to recommended standards as soon as feasible. Long pitches of steep grades that are carrying large water loads may still require steep out-sloping. This cross-slope must be designed so that it does not become a safety issue for trail users.

All constructed drains need to be well rocked, unless the landform can withstand water loads. When constructing drainage lenses or drain dips within the run of the trail, the area selected should be of large enough area to disperse water energy effectively. Focused drains, as in water-bars, tend to either clog rapidly, or create erosion problems at the outfall. Depending on pitch (steepness) of trail grade, and length, it may be advisable to add multiple drainage structures throughout the section. By adding drain-dips in a steep section of trail, water energy can be minimized. As the water slows, any material carried in transport drops out. Careful placement of drain-dips can actually result in adding material to the trail tread as it drops from the slowing water.

4.11 ROCK CONSTRUCTION

Use of rock structures in this region is preferable to wooden or other structure, as it will last forever (if done correctly). Construction of rock steps, rock walls, and rock foundations are not only durable, but also aesthetically attractive. Several types of rock construction are used in this region, and may depend on available materials. Stacked rubble walls can be used for erosion control and as retaining walls in relatively flat areas. Fitted rock wall, steps and foundations are done without mortar or cement, and are dependent on careful selection and placement of rocks. Rock walls (both rubble & fitted) need to have the proper amount of layback to function properly. Structural foundations, such as bridge footings, also need proper layback and placement. Rock steps need to be constructed using engineered step calculations, and correct sizing and fitting of rock.

Rubble, or stacked rock walls can be used as erosion controls and as retaining walls for trails or other structures. This type of wall serves well as an erosion control as it will allow some water flow, but will control high-energy water flows. By reducing water energy, transported soil material will drop from suspension in water and rebuild areas where soil has been lost. These types of walls are usually out of areas of visitor traffic and may be loosely constructed. Rubble / stacked walls used as retaining walls for trails or other facilities where visitor use is anticipated, need to be constructed so they will withstand more severe impacts. This construction need to be fitted to some degree to allow interlocking of rock. Construction needs to begin with large rocks for base material, grading to smaller material near the top. Small rock and fragments of rock should be used to chink openings between larger rocks and will further lock in the structure. Friable (easily broken) rock works well for chinking. If being built to retain any fill material, the wall needs to have sufficient layback against the weight of this fill.

Fitted rock-walls, foundations, and step carriage components need careful selection and fitting of rock. This type of work can be mortared or cemented in place if needed, however properly constructed rock structures normally do not require this unless there are difficulties in securing structure to bedding. Fitted rockwork needs to meet requirements of secure bedding, good edge contacts, and careful “breaking” of all joints. Sufficient layback of these structures is

APPENDIX K

K-19

important, with those structures built on sloping ground needing more pronounced layback. Chinking of gaps is advised with fitted rockwork, as well. This will enhance locking of larger rocks. Secure locking of cap rocks is also important, especially on retaining walls where visitors may dislodge them.

Rock steps require careful selection and fitting also. Rocks used for step construction need to be of sufficient size (> 80 lbs.) so they cannot be dislodged from set locations. It is also important to lock all edges so steps remain secure. Proper engineering of the step carriage is important. Wherever possible, step carriages should conform to engineered standards (rise & run). Some step carriage locations may not fit within standard calculations. If it is necessary to construct steps that cannot conform, it is important that all steps within run are uniform in both rise and run.

4.12 RETAINING WALLS

Retaining walls may be constructed for various reasons. Stabilization of slopes for resource protection and visitor safety, bridge and other structural foundations, and erosion control and capture of sediment may require retaining wall structures. Landform compatibility must be assessed prior to construction to determine suitability.

Retaining walls may be constructed of rock (fitted and stacked), manufactured block, lumber, or recycled construction material (Trex, etc.). The purpose of a retaining wall may dictate engineering standards for construction. Smaller walls built for minor erosion controls, trail edge stabilization, minor bridge and puncheon structures, and some of the less significant slope failures may not require extensive engineering; however, major structures may require construction to more severe engineering standards. Walls three feet and shorter as measured from the top of the footing to the top of the wall may be constructed without permits. Walls greater that three feet in height or supporting a surcharge will require a permit through the Development Services Department.

Correct degree of lay-back when constructing retaining wall is important. Additionally, construction of interlocking components of wall structure will increase load and holding capacity. Design plans for these structures are on file and available as needed.

In some cases, where retaining walls are to be constructed as a condition of other major facility construction, specific engineering standards may apply. As many walls may require substantial alteration of existing landforms, it is important to have a thorough understanding of constructions, and adherence to any regulatory guidelines or restrictions.

4.13 BRUSHING (TRIMMING)

Brushing, or trimming, is usually the highest maintenance task for most trails. Clearly defined trail corridors are crucial to safety, and may be critical to maintaining tread design and function. Trails not sufficiently brushed decrease line-of-sight, which increases potential user conflicts. Additionally, trails that become heavily brushed-in may cause users to “go around” vegetation and degrade the trail by creating a new, erodible, trail tread.

In this region brushing should be done annually in areas where vegetation grows rapidly (chaparral, mixed chaparral, etc). During yearly cycles with extensive rains, this brushing schedule may need to be increased. High use trails, and shared or multi-use trails need to be assessed regularly to maintain safe trail corridors.

Trail brushing may be variable depending on trail classification and use. Generally, all trails should be brushed 1 – 2 feet beyond the trail tread. Overhead brushing should be maintained at a minimum of 6’-8” to 8 feet in height for pedestrian and biking and at a minimum of 10 feet in height for equestrians. If overhead is maintained at less than 8 feet (for example, to maintain canopy cover common in scrub vegetation), the trail must be signed to indicate reduced overhead clearance.

In habitat zones with vegetation that typically does not grow to great heights (Coastal Sage Scrub, some Chaparral), brushing to less than 1 foot may be acceptable if brushing above 4 feet can be done to provide good sight lines. This reduced width trimming may be done to retain character of the trail while maintaining existing vegetation for soil retention (roots), and rainfall moderator (to reduce heavy rainfall directly on trail tread). An understanding of local conditions, including soils and vegetation, will determine brushing requirements in these areas.

Brush removal is usually fairly simple – “find the source”. This means to cut brush at the point where the overgrown vegetation begins. Some vegetation types may be cut using shears if cutting back to the source will significantly reduce vegetation. Hand tools such as hand-loppers, pruning shears, hand saws are normally sufficient for annual brushing; however chainsaws or other power equipment may be needed in some instances. City policy for chainsaw use guidelines will be followed at all times. Additionally, all City staff operating power equipment must be current in required certification (chainsaw).

4.14 TRAIL CLOSURES

Trail closures will normally be of two types:

1) Temporary closure

a) Repair, rehabilitation, or realignment

b) Biological (nesting / breeding season)

c) Seasonal (rainfall creating conditions where use would damage resources)

APPENDIX K

K-21

2) Permanent closure

a) Redundant trails

b) Unauthorized trails, including trail shortcuts (Note: Unauthorized trails that have not been “officially” approved/opened may be closed as needed without an official action.

c) Trails not accessible to the public

d) Trails not safe or sustainable

e) Trails facilitating illegal activity

f) Trails contributing to resource impacts: erosion, biological, other

g) New environmental concerns

Temporary closures will be done to complete trail repairs, construct special trail facilities as needed (steps, stairs, fencing, retaining walls, overlooks, etc.), or complete trail realignments. Additionally, trail closures may be initialized in some areas to accommodate biological concerns (breeding/nesting), or seasonal conditions (rain, mud). While it is ideal to close the trail completely during trail repair and construction periods, it may not be reasonable or feasible due to daily high-use patterns. Where it is difficult to affect a full trail closure, appropriate signage and other controls must be implemented to reduce hazards to trail users and trail crews. While this is usually not an effective option, and reduces productivity of trail crews, it is often necessary. All temporary trail closures should be scheduled to those times when user volume is low, during breeding/nesting season (if applicable), and when seasonal conditions are not favorable (rains, muddy conditions).

Permanent closures will be implemented on those trails identified as having one or more of the above listed closure conditions. Trails identified will be closed, stabilized, and passively or actively revegetated. Closures traditionally require signage (minimum), and barriers (cut brush, fencing, etc.). If trails identified for closure are recognized in Park Master Plans, Community Plans, or other guiding documents, alternate routes will be identified and constructed to provide for intended access. Permanent closure of specific trails or specific areas shown on City Council approved documents (Park Master Plans, Community Plans, etc.) will be supported with substantive documentation, and can be approved as a Mayoral action.

The primary goal of Open Space management in the City of San Diego is to protect and preserve sensitive natural and cultural resources. New trails, changes in trail use designations (single-use to multi-use), realignments to accommodate use changes, and other trail modifications that impact these resources will require compliance with all regulatory requirements.

4.15 STREET / ROADWAY CROSSINGS

Street and roadway crossings are common in the urban environment, particularly in the more developed portions of the city. While most crossings can utilize signaled or signed crossings where motor vehicles must stop, some crossings may occur in a mid-block. While the majority of these mid-block crossings primarily accommodate hikers, many may also include bicycles, and/or equestrians.

Mid-block crossing “at grade” should be avoided. Other crossing alternatives, such as bridges or tunnels are preferable if possible. If an “at grade”, mid-block crossing is considered, design must be implemented in compliance with the City of San Diego Street Design Manual, City of San Diego Council Policy 200-07, Caltrans Highway Design Manual, and State Traffic Manual.

Visual corridors, traffic speed and volume, and crossing users will factor in the determination of required safety controls. While many crossings are in urbanized, developed areas of the City, and have low traffic speeds and volumes, crossing controls may be minimal (signage). In areas that have high traffic speeds and/or volumes, and multiple users (including equestrians), crossing controls may include signs, flashing lights, and user activated signals. Appropriate City Departments will determine crossing requirements.

4.16 SIGNAGE

Regulatory: Signs informing trail users of rules, regulation, and restrictions and prohibited activities. Regulatory signs also provide for the safety of the user or to add to their enjoyment.

Interpretive: Signs providing interpretive, educational, or other trail information to the public.

Directional & Location: Signs that indicate location of user, direction of trails, linkages and connections, and mileage (when appropriate).

Signage should be standardized as much as possible, with design and color consistent with the Open Space environment. Signs should also be consistent with other agency signage (when possible) to provide for continuity and clarity of information. Current City sign inventory may need to be expanded to address changing conditions (usage, specific trail conditions limiting use, etc.).

Division SUBJECT: Policy on Avoiding Use of Non-Native Invasive Plants in Park & Recreation

Department Projects

PARK AND RECREATION DEPARTMENT POLICY

All future Park and Recreation Department projects, whether upgrades to existing

facilities or new construction, should avoid the use of any of the Most Invasive non-native

plants species listed in the Invasive Ornamental Plant Guide in any landscape, and should

avoid the use of any of the Moderately Invasive non-native species in landscapes located on

parcels adjacent to open space and/or Multi-Habitat Planning Area (MHPA) lands.

Most Invasive Plants: It is important to avoid the use of the Most Invasive species in any landscape because it has been documented that they may become established in open space lands from distant plantings. This is because plant seeds or spores can spread long distances through wind, water, or other carriers to reach open space. Moderately Invasive Plants: Moderately invasive species should be avoided in landscapes located on parcels adjacent to publicly-owned open space lands or open space easements, or the Multi-Habitat Planning Area (MHPA). The Invasive Ornamental Plant Guide identifies habitats in which a plant species from this list may be invasive. Exceptions: While every attempt should be made to substitute alternative, non-invasive plant species for those invasive species listed, in certain unique situations, such as, but not limited to, historic and/or significant landscapes which are not located adjacent to open space or MHPA lands, it may be appropriate to selectively use plant species identified in the Most Invasive and Moderately Invasive plant lists. In those specific instances, a justification letter approved by the Deputy Director of the appropriate Park and Recreation Department Division must be written and placed in the project file.

EXPLANATION

We are experiencing an invasion of non-native plants in over 70% of our 24,000+ acres of open space, which crowd out native plants and reduce the quality of habitats. Removing these non-natives once established is an expensive, time-consuming, and often not very successful process. Additionally, it is important that the Park and Recreation Department lead by example, comply with the City’s Multiple Species Conservation Program (MSCP), and be a good steward to the open space lands we manage and the MHPA preserve our parks are often adjacent to. The City’s MSCP Subarea Plan, Section 1.4.3 Land Use Adjacency Guidelines, states that adjacency issues must “be addressed, on a project by project basis, during either the planning (new development) or management (new and existing development) stages to minimize impacts and maintain the function of the MHPA…..No invasive non-native plant species shall be introduced into areas adjacent to the MHPA.” Recently, the San Diego Chapters of the California Native Plant Society and the American Society of Landscape Architects worked together to develop the attached Invasive Ornamental Plant Guide. The guide is a good resource for explaining characteristics of invasive plants and how they impact native plants, and provides a matrix list of Most Invasive and Moderately Invasive plant species that should be used either not at all, or, only in certain locations. We have included the matrix list as an attachment; however, we encourage staff to explore the website to learn more about invasive plant species and about the Invasive Ornamental Plant Guide (http://www.asla-sandiego.org/Download/PG_08_mod.pdf). We have also ordered copies of the California Invasive Plant Council Don’t Plant a Pest brochures for distribution to interested staff and the public. This brochure is a good visual and informative guide to what native or non-invasive plants can be used to replace species on the Invasive Ornamental Plant Guide matrix list. The brochure can also be accessed on the internet at the following web site http://www.cal-ipc.org/landscaping/dpp/planttypes.php?region=socal.
